MultiFunctionMathFindLocalMinimum Method (FuncIReadOnlyListDouble, Double, IReadOnlyListDouble)

Finds a local minimum of a multi-dimensional function in the vicinity of the given starting location.

Namespace: Meta.Numerics.Analysis
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4

Syntax

public static MultiExtremum FindLocalMinimum(
	Func<IReadOnlyList<double>, double> function,
	IReadOnlyList<double> start
)

Public Shared Function FindLocalMinimum ( 
	function As Func(Of IReadOnlyList(Of Double), Double),
	start As IReadOnlyList(Of Double)
) As MultiExtremum

public:
static MultiExtremum^ FindLocalMinimum(
	Func<IReadOnlyList<double>^, double>^ function, 
	IReadOnlyList<double>^ start
)

static member FindLocalMinimum : 
        function : Func<IReadOnlyList<float>, float> * 
        start : IReadOnlyList<float> -> MultiExtremum

Parameters

function: Type: SystemFuncIReadOnlyListDouble, Double
The multi-dimensional function to minimize.
start: Type: System.Collections.GenericIReadOnlyListDouble
The starting location for the search.

Return Value

Type: MultiExtremum
The local minimum.

Exceptions

Exception	Condition
ArgumentNullException	function, start is .
NonconvergenceException	The number of function evaluations required exceeded the evaluation budget.

Remarks

For two dimensions, the default evaluation settings target a precision of about 10^-8 and allow up to about 1000 function evaluations. For increasing dimensions, these requirements are gradually relaxed.
